I currently have a Noctua NH-D14 for my CPU, a Noctua NF-P14 for rear exhaust and another Noctua NF-P12 that sits on the floor of the case next to the PSU.

Here are the specifications of the fans I want to change (mainly due to the Thermaltake fans feeling cheap/ not moving a lot of air). Performance over looks, always.

Front intake: 200x200x20 (600-800rpm at 13-15dBa)

Side intake: 200x200x30 (600-800rpm at 13-15dBa)

Top exhaust: 200x200x30 (600-800rpm at 13-15dBa)

Does anyone have any recommendations on the fans I could get or any other information regarding air cooling please?

I'm thoroughly interested in all information in order to learn about and create great air flow so feel free to add anything even if it doesn't feel 100% relevant, the only thing I know is I need positive air pressure as dust builds up a lot in the house.

P.S There are 3 free bays at the front of the case, I ideally want to put an intake fan there and I've been thinking about replacing the NF-P12 (120x120x25mm) next to the PSU with a 140mm version and placing the NF-P12 in the bays for more intake, any comments/suggestions as to where I can get something like the link I post below in England?

Damn you though for making me check out more specifications of new fans haha, I keep constantly checking CFM, static pressure, reviewing positive air pressure etc etc.

All of those fans look great and do overtake the Noctua's in different areas!

I'm hoping the 120mm I've already got will be enough at the front of the case in the hard drive bays (once I find a mounting) but does air need to be gently pushed towards the NH-D14 CPU cooler from the front intake fan or should it be blasting away at it?

Apologies for the constant questions I'm just genuinely fascinated by anything that can increase performance!

Corsair they have the AF series for case fans, using the SP series on my rads both performance ratings, case fans have been too lazy to randr yet as case is new still. Have 4 waiting for when they get dusty or noisy or just piss me off in anyway...

I HAVE a selection of Corsair fans, both AF120/140 and SP120's. I would say they're not actually all that great. They do move a LOT of air, but they're not the quietest fans in the world, even with the included 5V resistor installed (without the resistor they're just noisy!). Reliability has been so/so. Out of 5 fans purchased, one of my SP120's failed after a few months and had to be replaced (Corsair rep was nice enough to send me a new double pack though, so it was resolved on their end).

I was looking into the Corsair but now not so sure haha, I've never heard anything bad about Noctua and I guess it's stick with what you know, it's just a shame they don't do 200mm fans (massive ups and downs with Bitfenix Spectre Pro vs CM Masterflow, no idea what to choose if to even replace the Thermaltake's at all).

Still haven't found a 120mm mounting for the 3 hard drive bays, does anyone have any home made mods they'd like to share?
